Li Qinzai's guess was correct, after the invention of landmines, the original strategy of the imperial court and ministers in Pingdong may have to be completely changed.

Landmines appeared in this era, and the greatest use is that they cannot be prevented.

It can be buried in any place, on any road, as long as there are enough of them, it can form an artificial Shura field, and enter the minefield to die or live, even tens of thousands of enemy soldiers, enough to trap them to death.

In addition to anti-personnel, landmines also have a role, that is, to create an indelible psychological deterrent to enemy troops on the battlefield.

For example, if someone in front of you strikes a mine and kills one piece, the people in the rear will only feel endless fear, and this fear can easily spread and amplify in a large army.

Once the fear exceeds the limit of psychological tolerance, it is normal for the enemy army to have a camp roar at night, the morale of the army has plummeted, and the combat strength has dropped rapidly, and the Tang army is as simple as cutting tofu to deal with.

As for how the enemy army would clear mines, Li Qinzai had already predicted.

If the army wants to clear mines, it can only choose to drive war horses, and the mountainous terrain of Goguryeo, as well as the current barren state of the country, it is destined that the number of war horses in the Goguryeo army will not be too much.

If the soldiers are used to form a death squad to clear mines, the effect is not great, not to mention, this method is more likely to make the officers and men of the army fearful, and the army has already mutinied before the mines are finished.

Li Zhi and the veterans obviously thought of this, and they were not worried about the enemy's demining at all.

Besides, the Tang Army's strategy is established, and the army is squeezing the living space of the Goguryeo Army step by step, where do they have time to clear mines.

Li Zhi witnessed the power of the mine with his own eyes today, and attached great importance to this object, and after carefully checking the radius of the explosion, Li Zhi looked up at Li Qinzai.

"At the beginning of the day, the manufacturing process of this thing can be complicated?"

Li Qinzai immediately obediently took out a few drawings from his arms and presented them with both hands: "The secret recipe for the manufacture of landmines is here, and I am willing to dedicate it to Your Majesty." ”

Li Zhi smiled with satisfaction, this thing is obviously sensible.

At this time, there is no need to pretend to be humble, in case this product is really not given.

So he unceremoniously took the secret recipe of the drawing, and Li Zhi put it in his arms without looking at it, anyway, he couldn't understand it, the important thing was that he had the secret recipe in hand.

"Sensible! Go back and bring me some beef, and I've finished eating the beef in the palace. Li Zhi whispered in his ear: "The cow on your Zhuangzi has been unfortunate recently, right?" I tell you, you have to die, you know? ”

Li Qinzai blinked blankly, what logic? Shouldn't the sensible be rewarded with something? Why take your own beef? Therefore, after being sensible, you have to be more sensible, so as to be worthy of the emperor's grace?

You're giving me a little favor.

"Your Majesty, the process of making mines is not complicated, just call a blacksmith to make molds and make a few delicate parts, as long as there are enough people, within two or three months, the mines will be ready for military use."

Pointing to the direction of Weishui at the east end of the village, Li Qinzai said again: "The minister once built a hydraulic press, Your Majesty might as well ask the craftsman to make it, this thing is used to make molds and make molds, which can get twice the result with half the effort." ”

Li Zhi's eyes lit up: "I almost forgot about the hydraulic press, yes, I can go down to Weishui to build a few workshops on the site, so that the craftsmen can go all out to mass produce mines, and strive not to delay the army's crusade." ”

"By the way, I seem to remember that Ren Er was once the young supervisor of the Firearms Bureau, didn't Jing Chu forget that he still has this official position? I haven't seen you ask about the Firearms Bureau in the past few years, huh? ”

Li Qinzai's eyelids jumped, and he hurriedly said, "Your Majesty, minister...... I just want to be a teacher. Regarding the mass production of mines, I also ask Your Majesty to appoint another meritocrat. ”

Li Zhi looked at Li Tao and said with a wry smile: "Look at Yinggong, your grandson obviously has a skill, but his temperament is too lazy, and others can't ask for officials all his life, but he is good, he doesn't take his official position seriously, he can hide everything if he can, and the donkey that pulls the mill is not as difficult as him......"

Li Tao said unhurriedly: "What Your Majesty said is very true, or ...... The old minister will kill him? ”

Li Qinzai was innocently frightened and looked at Li Tao in amazement.

Is it necessary to be so ruthless? Isn't he his own, an orphan picked up by Li Tao from outside during the war?

Li Zhi laughed: "Yinggong don't make trouble, how can such a person be killed, I still have to reuse him." ”

Saying that, Li Zhi looked at Li Qinzai and said: "You can't hide, don't you feel guilty about taking the court's money for nothing every year?" ”

"Jing Chu, I arranged an errand for you, recently the envoys of various countries entered Beijing to congratulate, and sat in Honglu Temple again and again to make trouble, saying that they wanted to enter the palace to see me, most of them wanted to ask for some benefits."

"There is also Tubo, about Tuyuhun is still not giving up, these vassal envoys will be handed over to you, you and Honglu Siqing will receive them, if you want benefits, you will not give up on Tuyuhun, you go talk to them, and send them as soon as possible."

Li Qinzai's face changed, and he blurted out without thinking: "Your Majesty, the minister suddenly committed a vicious illness, I'm afraid that time is running out......"

Before he finished speaking, he was kicked hard in the ass, and he didn't have to look back to know who the murderer was.

Li Qinzai had no choice but to change his words secretly: "Yes, the minister obeys the order." ”

Li Zhi pulled the corners of his mouth with a smile, it turns out that there is someone in the world who can cure you after all.

…………

The secret recipe for the mine was taken away by Li Zhi, and this matter has nothing to do with Li Qinzai.

As soon as the mass production was due, Li Zhi did not expect Li Qinzai to do it, since there were manufacturing drawings, mass production of mines was a trivial matter, Li Zhi could not make a big deal of it, and this kind of thing could be done casually by a capable official.

As usual, the monarch and the ministers had a sumptuous dinner in the courtyard, and the next morning Li Zhi and the veterans left satisfied.

The reason why they were "satisfied" was not only that they received landmines, but also because everyone also received souvenirs when they left.

That's right, for some reason, another cow in Ganjingzhuang unfortunately broke last night, and it was inexplicable.

Then the next day, the monarch and the ministers each carried dozens of catties of beef and left happily.

Li Zhi was the happiest, after all, the treatment of the Son of Heaven must be of high standard, Li Qinzai gave him nearly 100 catties of beef, and it was all beef tendon meat, which was very strong, enough for him to eat for a few months.

Standing at the entrance of the village, he respectfully sent the monarch and his ministers away, and it was not until their cavalry disappeared at the end of the road that Li Qinzai sighed secretly.

"I always feel like something is wrong...... Why do I feel a sense of grief and anger after being robbed? Li Qinzai muttered.

The mine drawings that I worked so hard to get out were given away......

Zhuangzi also lost a cow and was divided among the great powers......

The leisurely life of a teacher in a mountain village was inexplicably arranged for an errand, and he had to go to Chang'an to deal with the group of wild monkeys......

And then, what did Lee Chin-jae get?

By the way, Niu Wei can't survive if he breaks his feet, and the Weinan County Ya will send officials to the door and fine him 200 yuan......

One after another, they are all deceived and deceived.

"I've been feeling a little unlucky lately, I have to find a god to worship......" Li Qinzai looked up to the sky silently.

Shaolin Temple in Wudang Mountain Office Grand Priest Wang Lama...... In short, no matter which way the gods are, it just works, and if it doesn't work, they will demolish their temple.

The incense money should be given, and if you take the money, you must do something for me, and there is no reason to waste it.

Holding the second child in the family, I feel that the second child is a natural fortune person, and he may have the blessing of spiritual power, and his wealth will be more prosperous.

By the way, it's time for the little bastards to double their tuition fees next year! Let your old man divide my beef unscrupulously!

…………

Li Zhi made an order and did not dare to disobey it.

The next day, Li Qinzai led his troops and reluctantly rode away from Ganjingzhuang and headed for Chang'an City.

There were many envoys from various countries who entered Beijing this time, in addition to the Tibetan Wa Kingdom and Silla, there were also many small surrounding countries, and some of the small country names Li Qinzai had never even heard of.

Li Qinzai's identity is regarded as the Son of Heaven, and he receives envoys from various countries on behalf of the Son of Heaven.

This errand is not fattening, after all, small countries are poor, and they can't squeeze any oil and water.

The Tibetans can focus on it, and it seems that the Wa Kingdom and Silla can barely squeeze out a little.

Li Qinzai and his subordinates entered Chang'an City, and after thinking for a while, they went straight to Honglu Temple.

Honglu Temple is dedicated to handling the affairs of various countries, which is equivalent to the Ministry of Foreign Affairs of the Tang Dynasty. Of course, the official activities and ceremonies between the two countries need to be participated in and led by the Ministry of Rites.

Enter Yanping Gate, pass through Changshou Fang, and then come to Suzaku Street.

There are still a few miles away from Honglu Temple, and suddenly I saw a crowd gathering in front of me, but I heard someone scolding loudly from a distance.

Li Qinzai blinked, and suddenly became a little excited.

It is the nature of the Chinese people to see the excitement, and Li Qinzai, who is the most respected county magistrate, is not exempt from vulgarity, where does the experience of life come from? Of course, it comes from watching the excitement, otherwise? It is impossible for people to experience every strange thing in person.

"Ah Si, open the way." Li Qinzai immediately ordered.

Liu Asi knew the temperament of the fifth young man, so he led the trilogy to slap away the passers-by who blocked the road with a scabbard, and instantly opened up a spacious and unmanned avenue for Li Qinzai.

The rude way of opening the way attracted the dissatisfaction of passers-by, but seeing the murderous appearance of the tribesmen, they had to restrain their temper and hide to the side obediently.

In order to let Wu Shaolang watch this excitement, Liu Ah Si was also very attentive, opening the way to the center of the crowd, leaving Li Qinzai with the best viewing position.

Li Qinzai swaggered over, stood in the inner circle of the bustling center, and began to watch with his arms around his chest.

In the open space in the middle of the crowd, several parties were making a fuss, but they were overwhelmed by Li Qinzai, an onlooker, and several people looked at Li Qinzai blankly.

"Go on, don't care how I feel." Li Qinzai commanded.

Parties: "............"

Of course we don't care about how you feel, but do you really care about how we feel?

We can't get it, you know?

Li Qinzai looked at several parties involved in the incident, and then his eyes narrowed, and he found that there was a person who was very familiar, and he recalled it carefully for a long time, but he still didn't remember it.

"Pause, you, don't look around, it's you, you look cold and dress cold...... Come here, do I know you? ”

It is indeed an acquaintance who looks cold and dresses coldly, and when he heard this, he smiled bitterly, and stepped forward to give Li Qinzai a long look.

"Student Wei Zhenzai, meet Li Xiangong."

Li Qinzai blinked, and then suddenly said: "It turned out to be you!" ”

It's really an acquaintance, not too familiar.

The last time Li Qinzai was the chief examiner of the imperial examination, it was also on this Suzaku Street that Wei Zhenzai, a national supervisor from a poor family, had a dispute with a certain son of a certain family, and the dispute even rose to the point of which had a better chance of high school.

Li Qinzai vaguely remembered that this Wei Zhenzai did well in the Ming Jingke exam, and he seemed to be in the top 20 of the second class.

Facts have proved that Wei Zhenzai, who was born in a poor family, is very competitive, and his talent cannot be concealed under the premise of no shady scenes and dark box operations.

Li Qinzai looked at Wei Zhenzai and said, "It's you again, why are you all the time?" What did you do this time? ”
